William Hamilton Meeks, III (born 8 August 1947) is an American mathematician, specializing in differential geometry and minimal surfaces.

Meeks studied at the University of California, Berkeley, with a bachelor's degree in 1971, a master's degree in 1974, and a PhD in 1975 with supervisor H. Blaine Lawson and thesis The Conformal Structure and Geometry of Triply Periodic Minimal Surfaces in

[3] He currently is at the Institute for Advanced Study after assuming professor emeritus status at UMass Amherst.

[4] He is known as an expert on minimal surfaces and their computer graphics visualization; on the latter subject he has collaborated with David Allen Hoffman.

[3] In 1986 at the International Congress of Mathematicians in Berkeley, he was Invited Speaker with talk Recent progress on the geometry of surfaces in
